I'm not trying to take sides and 9202s are my favorite servo but I have actually broken 9202 gears on a Raptor 30 with the upgrade pitch arm. We're talking from hard flying not crashing. I've also broken motors from the pcb in 3001s (good thing they're cheap). The 9202s are great but on collective I feel better with something like a 9204 or 9206. That's like a super mac daddy servo. Anyway, nobody's wrong here just giving my 2¢.

If I experience a woof the first thing I'd change are the blades as I'm sure you have. I have a friend that also has the dreaded sce-woof. He's tried different blades with various results but the common denominator seemed to be related to overspeeding the blades. If you can, tach the head and check your speed.

Lately (Past Month) I haven't been having problems. I may upgrade to the evo head anyway, but I will see. The headspeed was a little high, and it was lowered. I also put the plates on. It hasn't woofed on me yet, altho I haven't been doing anything aggressive. If it does it again I will get the evo head.

Thanx everyone

Hi guys,
I have the Woof/Poof problem only when I switch it to idle up 1,
I had just upgraded to EVO Head, though it will solve my problem.
IT DOES NOT. and it causing the spindle to bend ( 4 pcs bent)
I am using 9202 for the pitch. 600mm MS blade
Still trying to solve the problem by
1) Changing the pitch servo
2) stiffen the damper by putting more washer between the blade holder.
3) reset all the connecting rods

Hope it work !
any advise ?

Neo

I'm not the expert but I think the MS blades are a "no no" for this heli. Borrow some different blades if you can to check it.

I would grip flip it. That is not a cure, but it does help with some. Sending Ross's back is not an option.

I've installed push pull kit on mine and it solved the problem.No more blades going out of track no matter what I do.
No if I can get the better engine ,so I can ge more power.Webra in my sceadu is too old.
Here's the crazy idea.Any of you guys tried put 60 in sceadu?I was messing around today and I think it can be done.OS 61 will fit in,just the fan will have to be modified.
What do you think will happen?

Keep the 9202, mount the pitch servo per the instructions, don't hack or shave anything, get a governor and try the MS blades again at 1750 headspeed. I'll bet the woof goes bye bye. My STOCK unhacked non-evo sceadu 50 had woof, I say HAD woof many many gallons ago. I don't even worry or think about it anymore since I governed it and have the headspeed controlled from unloading.

Good Luck.

zsparks, all good suggestions, but Ross's helicopter is hovering at eye level, one constant rpm, no head unloading.

I guess I was reading that when he initially got the woof it was when the engine leaned. This to me would indicate a possible overspeed resulting in the woof that can be controlled by governing. When my sceadu would woof it would be unprovoked at times and other times a result of unloading in descent. Either way I don't have it anymore and my setup is still stock with a governor addition.

I do primarily fly SAB Carbons on mine but I do have some MS blades and the MS blades are no worry to me for woof. My SAB blades would woof but only when the headspeed zinged way up on fast descent. I got the MS blades after the governor and they have never woofed. I did have the Mavrikk blades prior to governor and they woofed just looking at them. I would like to try them again now that I have the governor but I just don't want to spend the money on them when I don't really need them.

Good Luck

MAH 600's

Hi,

I've been flying the MAH 600's (605's?), and my sceadu is flying flawlessly. Tracks well, no woof, but I do have a govenor on mine. The sceadu is very deceiving guessing headspeed. I had someone tach me prior to the govenor and was flying around at 1950 I thought it was around 1750...

Good Judgement comes from Experience. Great Judgement comes from Bad Experience.

Hey guys - very little comment about head speed. I bent a spindle and a feathering shaft when I let the head speed on my Sceadu creep up. I made lots of adjustments in the course of trying different blades etc over a few weeks - suddenly I had a problem. Turned out idle up 1 had crept up to 2200 head speed - wound it back to 1800 and all my problems went away. Should have used the tacho to check headspeed.
Worth a check .

Sceadu woof and poof

Dude! Save yourself a lot of frustration and some $. Just flip the head
same as the Raptor flip, took all of 30 minutes including setup of the pitch curve! Smooth as silk! I had V blades that I trashed in a crash, put on Mah on the rebuild. They would do fine spooling up, but with the least amount of decrease in power setting, they went "violently" out of track. I had already been through everything that could possibly be thought of with no improvement. I flipped the head and "voila"!!! Smooth as silk all the way through the pitch and power curves regardless of where I set them. I can overspeed the h--- out of them and pull off power and they stay in track! Just my .02!
Thanks,
Keith

The grip flip sometimes works, sometimes does not. Please don't toot it like the cure all, fix all.

All I have to say is that when I ran my TT600 blades mine flew fine at 1500 to 1800 rpms. After my tank leaned out the head speed went up and and it would start to woof. I went and tightened down the arms by shimming and filing. Then I put the evo 50 conversion on my sceadu running the same blades and I can run them at lower or an outrageous rpm and still has no woofing. I would convert it to the evo just for the simple fact that it flies better with the conversion. Just my .02 cents!

Hi guys,
Woof/Poof problem solved,
I checked all the connecting rods and do a reseting on all the set up.
Do not have any loose connecting rod. Double check!

Thanks
